IMPROVEMENT IN GATES.

Specification forming part of Letters Patent No. 189,814, dated April 17, 1877; application filed February 8, 1877.

' of Kane, Green county, Illinois, have invented a new and useful Improvement in Gates, of which the following specification is a clear and exact description, reference being made to the accompanying drawings, which form a part of the same.

Figure 1 is a side view of the gate partly opened. Fig. 2 is a sectional view of the gears and their supporting brackets, by means of which the gate is operated. Fig. 3 is a top view of the lower hinge.

The object of my invention is to produce a cheap andeasily-operated gate, that can be put up in any place, and not be liable to get out of order. v

A is the base or foundation, and B B are the upright posts in the same, to one of which the gate is hinged. -O is the gate proper, having vertical end pieces 0 d, and horizontal boards f. To the upper end of the end piece d is fastened a metal cap, projecting from which is a wrist-piece, e, turning loosely in a bracket, D. This bracket has two upright arms carrying a shaft, h, upon which is a beveled cog, 9, that meshes with a beveled cog, i, on the upper end of wrist-piece c. To the outer end of the shaft h' a removable lever, j, is attached, and in its upper end is an eye, through which the operating-cord passes to operate the lever and gears toturn or swing the gate to and fro. Upon opposite sides of the gate are posts E, having in their upper end eyes 70, for the operating-cord to pass through.

The bracket D has extending from its'rear a horizontal pivot or shaft, H, which turns in a socket, I, fastened in the top of one of the posts B. The shaft H may have a nut or pin upon its rear end to prevent it from drawing out. J is the latch, arranged between the boards or horizontal bars of the gate, and is pivoted at its inner end midway of an upright bar, is, which is, in turn, pivoted at its lower end to one of the boards, and has at its upper end an eye to which the ropes or cords thatoperate the gate are attached, so that the latch can be drawn backward to release the gate before it is swung.

A spring, m, is situated in the rear of the lever is, which constantly presses against it and keeps it in the forward part of the bracket a, save when it is overcome by drawing upon the cords. The lower hinge 0 has two semicircular holes, which, when the gate is closed, rest upon the pintles p p, but when the gate is swung in either direction, by drawing upon the cords, the outer end of the gate is raised, on account of its lower hinge turning upon only one of the pintles p, and therefore the gate is raised over the snow or other obstruction, and is closed by its own weight, and latched automatically.

The cord or cords 0 that operates the gate is fastened by a knot at its middle to the eye in the upper end of the latch-lever 7c, and one end of the cord runs back and passes through an eye, 3, upon one side of the post B, and. thence up through the eye in lever j, and passes side, and through'an eye in the post E.

The operation ofthe gate is, in short, as follows: One of the handles a: is seized and drawn, which withdraws the latch from its catch in the outer post B, and by further drawing of the cord the bar j, is pulled forward, which turns the gear g, and it, in turn, turns the gear i, and, as the latter is rigidly attached to the wrist-pin e, the gate is caused to be swung open in the opposite direction from the thus becomes released and the gate closes of its own weight.

An important feature in this class of gates is the shaft H, which permits the bracket D to turn in the socket I when the gate is opened, whereby I secure the advantage of having the lower hinge double, and the gate elevating and sell-closing.

My gate may 3 be constructed differently 2. A .gatc, 0, having I lower hinge 0 0, in from wh at Ihave described, it'i's cvident,= withi-z combination with a'b'racket, D,rhavingfia tnrnolit departing from the spirit of my invention. ing-sh'a'ft', H, and suitable gears 'y' '5, asset What I claim, and desire to secure by Letters forth.

Patent is GRANVILLE J. TINSLEY. [L. s.] 1. The combination of the bracket D, shaft Witnesses: h, gears g i, shaft Hflever j, and'the gateO, GEQDL HAYDEN;

as set forth. OLIVER W. MONTROP.
